IGNITE-7918: memory leak was fixed. Unit test was added.
Some caches didn't take into account that topology minor version could be
changed during creating/destroying of the caches dynamically. These places were
fixed.

> Dear Igniters,
> We observe huge memory leak when data streamer used together with local cache.
> In the attached demo producer produces local cache with single binary object
> and passes this to the queue. Consumer picks up the cache from the queue,
> constructs different binary object from it, adds it to global partitioned
> cache and destroys local cache.
> This design causes a significant leak - the whole heap is used within minutes
> (no matter if this is 4G or 24G).
